Utilization of fine needle aspiration cytology(FNAC) in the diagnosis of odontogenic tumors seems to have little attention. Ameloblastoma is the most common epithelial odontogenic tumor. However, the cytologic findings of ameloblastoma are described recently. We report a case of ameloblastoma diagnosed by FNAC. The aspirated blood-tinged mucoid fluid from maxillary mass showed a few clusters of tumor cells with distinct two-cell population: basaloid cells with palisading arrangement and squamous cells with more abundant and eosinophilic cytoplasm. Nuclear atypism, pleomorphism or mitosis were absent. A few keratinized bodies in the tumor cell clusters and the third component, stellate cells were also characteristic.
